    摘要： A secondary load path assembly comprising: a secondary load path comprising: a plate (60); a secondary nut (70); and a transfer plate (65) secured to the plate (60) and configured to connect the plate and the secondary nut in load transfer engagement, the transfer plate (65) having an opening (650) therethrough, an axis defined through the opening, and the secondary nut protruding axially through the opening; wherein, in a state in which load is not transmitted via the secondary load path, a clearance is provided between the secondary nut and the opening;
    the assembly further comprising: a locking unit (80) configured to lock the secondary nut to the transfer plate when load is to be transmitted through the secondary path, the locking unit comprising a lock (100) arranged to axially move to a lock position in which it is located in the clearance between the secondary nut and the opening to lock the secondary nut to the transfer plate.

    摘要： The present disclosure relates to the technical field of aerial work platforms, in particular to a linear actuator with a contact type safety nut, and an aerial work platform. The linear actuator includes a central screw, a driving nut mechanism, and a safety nut mechanism. The central screw has a screw raceway. The safety nut mechanism includes a safety nut seat sleeved at the periphery of the central screw. Limit hole channels pointing to the central screw are arranged on the safety nut seat. An elastic buffer element is arranged in each of the limit hole channels. A safety ball is arranged between the elastic buffer element and the central screw. The contact type safety nut enables the linear actuator to always keep safety, stability, and no loss of accuracy in a conversion process that the safety nut mechanism gets involved to take effect while the driving nut mechanism fails.

    摘要： A ball screw device includes a screw shaft, a nut, and a plurality of balls. An outer peripheral raceway surface is provided on an outer peripheral surface of the screw shaft. The nut is provided with an inner peripheral raceway surface in an inner peripheral surface and penetrates the screw shaft. The nut has at least three or more circulation components. A raceway has at least three or more ball circuits respectively corresponding to the circulation components. The at least three or more ball circuits include a central circuit placed at a central portion of the nut in an axial direction parallel to a central axis of the screw shaft, a first circuit placed in the first direction with respect to the central circuit, and a second circuit placed in the second direction with respect to the central circuit. In the outer peripheral raceway surface, pitch diameters of the threads are the same. In the inner peripheral raceway surface, a first inner peripheral raceway surface that belongs to the first circuit and a second inner peripheral raceway surface that belongs to the second circuit have different pitch diameters from a central inner peripheral raceway surface that belongs to the central circuit.
